Amino Acids and Peptides

Amino Acid and Peptide Analysis

UltraSep ESD AP

The column is suitable for the separation of derivatives of amino acids (A) and peptides (P). The common procedures are summarized in the following table. If samples are not often analyzed, esp. DABSYLchloride shows advantages.

DABS = DABSYLchloride (Dimethylaminoazobenzenesulfonylchloride)
OPA = o-Phthalaldehyde
FMOC = 9-Fluorenylmethoxycarbonylchloride
